@nimh tat-trs @einer Letters .Patent Nol 75,584, dated March 17, 1868. v

To ALL Weet/LITl MM?-fcoNeriRN=4 A' Be it known that I, MATHEW SENIOR, of Frankford, in the county of Philadelphia, and State of Pennsyl- Vania, have invented a. new and Vimproved Lubricating-Device; andI do hereby declare that the following is a A full, clear, andjexactldescription thereof, which will enable those skilled in the art to make and use the same 5 reference being had to themaccompanying drawings forming part of this specification. This invention relates to a new and useful devicefor lubricating the feather of a shaft, which has a longitudinal as well as a rotating motionimparted to it, for certain `mechanical operations pand it consists in prov -viding means for lubricating the shaft and the feather, as will be hereinafter described.

The drawing vrepresents e. vertical'section of thearrangement, showing the supporting stand, the revolving tubular journal, and feathered shaft. v i

fA is the stand, B is theY tuhularjournal, is Vthe shaft, and-ll) is the feather on the `shaft, which works in a groove in thejournal. On the end of the shaft is what is called a"f rubber. and the drawing is af section of the bearing of the.improved rubber condenser. About fourteen'.A of these feather-shafts 'are used in one' condensing-machine, an d the feathers are very liable to wear out, in consequence of the difculty of properly lubricating them. p

4 i The old method-of -oilingthe feather is to pour oil ofi the feather and shaft outside of the journal, and allow itto work its way towards the centre from each end. This but partially accomplishes the object, as most of the oil drips off without entering the hollow journal, while the oil, which" thus drips, down, falls on to and smears the machinery below.

By boring oillholes through the tubular journalv B, as seen in the drawing, (e e,) so that the feather receives oil `from twosources (or on each side) at each revolution, the object is accomplished, the feather beingperfectly i lubricated and preserved. The oil is poured into the oil-hole f'through the cap g, and entering the holes `e e,

works from'thecentre or middle portion of the shaft towards the ends. H is a gear-wheel on the hollow journal B. Jie the rubber on the shaft C.

Having thus described my invention, I elaimas new, and desire to secure by Letters Patent- VImb'ricating'the feather D upon the shaft C from each side of said feather, through the`holes e ein the tubular journal B, and theholef in the hollow cap g,` as herein described for the purpose specified.

MATHEW SENIOR.`
